-3 - 4 (t-5) = -2(t+3) + 11
Answer by gonzo(654)   (Show Source):
You can put this solution on YOUR website! if i understand this correctly, it is
-3 - 4(t-5) = -2(t+3) + 11
there are different ways to approach it, but this way works on this equation.
-----
first multiply out to remove the parentheses.
-3 -4t + 20 = -2t - 6 + 11
combine like terms.
-4t + 17 = -2t + 5
add 4t to both sides of the equation.
17 = 2t + 5
subtract 5 from both sides of the equation.
12 = 2t
divide both sides of the equation by 2.
t = 6
-----
to prove, substitute in original equation
-----
-3 - 4(6-5) = -2(6+3) + 11
simplify expressions within parentheses.
-3 -4(1) = -2(9) + 11
perform operations to remove parentheses.
-3 -4 = -18 + 11
combine like terms
-7 = -7
-----
answer is proven correct.
answer is t = 6
